IMPROVEMENT IN TURBINE WATER-WHEELS.

Specification forming part of Letters Patent No. 135,707, dated February11, 1873.

To all whom it may concern:

Be it known that I, WILLIAM P. HALE, of Lockhaven, in the county ofClinton and State of Pennsylvania, have invented certain new and usefulImprovements in \Vater-VVheels; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon which form a part of this specification.

The nature of my invention consists in the construction and arrangementof awaterwhcel, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a perspective view, and Fig. 2 is a vertical section, of theentire wheel. Fig. 3 is a plan view of the wheel proper with the topplate removed.

A represents the bottom rim of the wheel, made in the shcpe of anannular ring, upon which stand the buckets B B, and upon said bucketsrests the top plate 0. The buckets B B are made on a true circle ofone-half the diameter of the wheel, and stand perpendicularly up anddown, discharging the water on the outside of the wheel. The outer edgeof the top plate 0, where it rests on the buckets B B, is made perfectlyflat or horizontal, while inward from the same it is inclined downward,forming an inverted cone, and in the center thereof is secured the shaftD, which rests on the step E. G represents the curb underneath thewheel. The water comes in on one side of the curb Gr under the wheel,and rises up on an inclined scroll, H, within the same; and the underside of the Wheel being on an angle, as

described, the water is forced outward to the buckets. The scroll H runsin the opposite direction to that of the buckets, which causes a directaction and a reaction at the same time and the water entering on theinside of the wheel under full pressure, and discharging on the outsideof the wheel without any back pressure, gives a greater amount of powerthan it would otherwise have. In order to increase the size of thedelivery of the buckets, the top plate 0 inclines downward toward thecenter, thus allowing the buckets to be placed in a perpendicularposition, and thus delivering the water at the side of the wheel. Thecurb G projects upward on the inside of the wheel the thickness of thelower rim A, as shown at a a, and this lower rim of the wheel projectsdown over the rim of the curb, as shown at b 1), thereby causing tworight angles in the only joint there is for any water to escape. Thepressure of the water on the under side of the wheel relieves thepressure and friction on the step.

I am aware that perpendicular buckets, combined with a bottom rim and aconical top plate, have been before used. I do not, therefore, broadlyclaim such device; but

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The water-wheel provided with the rim A and buckets B B, formed on acircle of onehalf the diameter of the wheel, and the conical top plate0, and used in combination with the interior inclined scroll H, allconstructed and arranged as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

IVILLIAM P. HALE.
